To all whom/t may concern: as shown in Fig. I. Each concave is providedBe it known that I, MICHAEL MORAN, of the with a number of ribs 12,which extend beyond city of St. Louis, in the State of Missouri,have theface of the concave. These ribs are prefinvented a certain new anduseful Improveerably made of stiff leather, and they are also 55 5 mentin Machines for Removing Lint from preferably provided with bristles13,as shown Cotton-Seeds, of which the following is a full, in Fig. VI.The concaves are recessed, as clear, and exact description, referencebeing shown at 14, to permit the ribs to yield backhad to theaccompanying drawings, forming. wardly.

2. In a machine for removing liber from' seeds, the combination of ahousing, cylinders located within the housing, and having bristles ontheir peripheries, concaves located beneath the cylinders, yielding ribssecured to the concaves and projecting into the cylinder, and havingbristleson their free ends, and an exhaust fan, substantially as and forthe purpose set forth.
